Title: Making cylindrical laminated tanks of non-circular section - by distorting an open ended tubular body to fit prefabricated caps
IPC: B29C53/42
Filed: 1973-10-05
Abstract: Cisterns or vats made by bending and edge bonding a flexible sheet of laminated reinforced resin to obtain a straight hollow body and then distorting that body to match the profile of at least one rigid prefabricated panel which forms a cap or bulkhead defining the cross-sectional shape of the vessel. The components are bonded together by curing then completed. The process is used for mfr. of reservoirs of maximum capacity w.r.t. some size location or access, e.g. a cave mouth. Initial lay-up as a flat sheet allows extra material thickness to be laid up in those zones which will be relatively highly stressed in the end use shape or position of the tank, unlike vessels produced with uniform or symmetrical wall thicknesses as unitary wound structures on mandrel lay-up equipment. Access holes, etc. may be generated before or after assembly.

Title: Flexible brush carrier - for small motors for driving windscreen wipers is used to overcome alignment errors
IPC: H02K5/14
Filed: 1973-10-30
Abstract: The end-plate of this carrier has three fixing screws (3) for attachment to the mounting surface; it also carries the end bearing at its centre for the rotor of the motor. Three spigots (5) project from this plate and mate with three flexible mountings (8) in the brust carrier which is formed by a separate plate.

Patent FR-2310970-A1 (FR)
Title: Curved grating cleaning comb for water treatment inlet - self cleans and retracts automatically to prevent overload damage to grating
IPC: B01D29/01
Filed: 1975-05-16
Abstract: The grafting is cleaned by a combing rake fixed at the end an arm pivoting on a horizontal axis. The comb is automatically retractable, pref. against adjustable spring-loading, if it encounters an obstruction offering resistance sufficient to threaten damage to the grating and, as the comb rises to the end of its cleaning stroke, it meets a pivoted shovel which scrapes collected waste from the comb and drumps it clear of the treatment area. The shovel is pref. fixed to arm pivoted on a horizontal axis and is lifted by the comb at the end of its cleaning stroke, the weight of the shovel holding it against the comb while continued movement of the comb ensures a relative scraping action between comb and shovel. The cleaning action is completely automatic and dependent only on the movement of the comb. The construction is simple, inexpensive and trouble free. The grating is protected against excessive cleaning force.

Title: Current limiter with superconductive coil - uses coil natural magnetic field for change-over from superconductive to normally conductive state
IPC: H01L39/00
Filed: 1975-07-24
Abstract: The superconductive coil of the current limiting device can be switched by its natural magnetic field from the superconductive to the normally conductive state. The coil is surrounded by a magnetic screens of superconductive material which forcibly extend the magnetic lines path generated by the coil current. The partial cancelling of the screening effect results in the increase of the natural magnetic field, due to shortening of the path of the force lines, so that the coil is switched from the superconductive into the formally conductive state. The screens (4) can be at least partly subjected to a current surge and they are connected to a capacitor via an ammeter.

Title: Brazing, welding or soldering wire - helically wound to form flexible tube which is filled with flux
IPC: B23K35/40
Filed: 1975-12-11
Abstract: Wire for brazing, welding or soldering is made of a suitable metal or alloy and wound into a helix so the turns are in contact with each other and form a flexible tube which may or may not be filled with an etching flux. A metal wire can be inserted in the tube to increase its rigidity if required. The pref. method of filling the tube with flux is to place the tube in a bath of flux held in a closed chamber; pressure is then applied so the liq. flux is forced between the turns of the helix which are driven apart by the press. so the flux enters the bore of the tube. The tube is subsequently washed and dried so flux on the outside of the helix is removed, leaving the bore filled with flux. The tube formed by the helix contains the correct amt. of flux so the latter does not have to be added separately during brazing, etc., and the tube is flexible so it can easily be wound on a spool and used on automatic brazing machines.
